Cerberus Island

I started the map twice with a Hero, but I couldn't get past Orson's attacks. The map is difficult to clear, especially in the first week. I don't understand how to complete it without war machines, which I can't seem to get.

Thank you for playing my map! I've just started the scenario again with a Hero, and it started normally without managing war machines. Perhaps it's easier for me because I've played it many times and developed a certain strategy. Or maybe there are some really bad scenarios that I just haven't encountered. You can try it on Veteran difficulty for now.
